So a lot of people have been going on about Redworx being VAC detected. Then I read a post saying the people who got VAC banned were the ones who used older versions of the cheat where they got added to a delayed ban list months before hand.
Although you will not get VAC banned for using the program, you must be sure NOT to use rage mode or putting your FOV too high. Failing to do so will grant you an Untrusted ban which will turn into VAC ban. So in terms of detected, yes and no
No as in VAC anti-cheat scan will not detect your hacks but yes as in they will be able to trace things such as different inputs it receives from your mouse compared to in-game, starring at a wall too much, aiming at a certain bone too much, etc
